ENGINE REPAIR STAND.

Application filed December 18, 1922. Serial No. 607,593.

To all whom it may co /warn:

Be it known that I, VioToR BLASEZYK, a citizen of the United States, residing at New Rome, in the county of Adams and State of Wisconsin, have invented certain new and useful Improvements in Engine Repair Stands, of which the following is a specification.

This invention relates to a support or stand to hold parts of machines while beingrepaired, or otherwise operated on, and has for one of its objects to simplify the construction and increase the efficiency and utility of devices of this character.

Another object of the .invention is to provide a device of this character which may be readily adjusted to fit parts of machines of v various forms and sizes, and wherein means are provided for securely holding the parts in position against strains incident to the repair operation, or the like.

Another object of the invention is to provide a device of this character including a rotatable mandrel or shaft adapted to apply rotary motion to a crank or other shaft to regrind bearings, or to burn in bearings or for like purposes, and holding the article bein acted on firmly in position.

With these and other ob'ects in view, the invention consists in certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claims, and in the drawings illustrative of the preferred embodiment of the invention Figure 1 is a perspective view of the improved apparatus arranged for operation on the crank shaft of an internal combustion motor.

Fig. 2 is a perspective view showing the improved apparatus arranged to supportthe rear'axle of an internal combustion motor.

Fig. 3, is an end elevation of the improved apparatus; i

Fig. 4 is a plan view of the improved apparatus.

Figs. 5 and 6 are enlarged details of two of the supporting attaohements.

Fig. 7 is an enlarged'detail illustrating the engine bed holding means. Fig. 8 is an enlarged detail of a modified form of holding vise. I 1

Theimproved apparatus comprises a supporting stand including upper horizontal rail members 10 extending in parallel relation and leg or standard members 11 of any suitable construction.

Mounted on the rail member 10 at one end are standards 12 and 13 in spaced relation and having bearings 14 and 15 for supporting a shaft or mandrel 16.

The mandrel carries a band wheel 17 which is also the outer member of a friction clutch, the opposing inner clutch device being indicated conventionally at 18 and including an operating lever 19. By this means the motion of the mandrel is controlled.

Attached to, or integral with the mandrel 16 is a head or face member 20 having spaced pins 21 extending therefrom as shown.

Connected atthe ends to two of the leg members are spaced guide rods 22, and slidable onthese rods are a plurality of bars or head members 23 through which a threaded rod 24, extends, the latter having a crank arm 25 at the lower end.

At one end one of the members 23 is provided with an extension 26 swingingly coupled to one of the members 23 as shown at 26 and adapted to be turned vertically, as shown in Figure 7, to form a stop to bear against the bottom of an engine bed when the latter-is turned on its side, to assist in holding the'bed in position while operating on the cylinders and valve seats.

The members 10 constitute base rails to support the "work being operated on, for instance the cylinder body 27 of an internal combustion motor, the rod 24 being utilized to support the cylinder body in position with its crank shaft 28.

The supporting members 23 are preferablyprovided with a plurality of threaded apertures for the rod 24 as indicatedin Fig. 4, to enable the rod to be adjusted for different forms of engine beds.

The supporting rails 10 extend beyond the tail standard or leg member 11, and attached as by bolts 29 to the under faces of theextended portions of the rails is a base member '30, the latter extending at its ends beyond the side edges of the rails, as shown. Rising from the member 30 at one end are spaced standards 31 having angular recesses 32 in their upper ends to form rests for a body to be operated on, for instance the of an internal ably receivevarious forms of standards carrying "various forms of supports: For instance one standard,represented at 35 in s Fig. 5, is provided with a block or transverse head 36 having "a longitudinally directed j bore,-to receive a rod 37 threaded at one end to" receive a wing nut 38, the block having an upwardly opening slot indicated at'39 andthe rod having an upturned end 40 ex- 7, tending through the slot end for some distance above the upper face of the block, and

the block also provided with a stationary pin 41' near the unslotted end.

'5 The member is provided with means i. -suchv as a set screw 42 operating-against the standard when in the socket 34, to hold it :-the standard in position vertically.

The'block or head 36 is designed to support. a bearingcap in reversed position while 30 Zing the bolt, apertures of the capand holding it from. lateraldisplacement. By arranging the pin for adjustment longitudinally being operated on, the pins 40 and 41 enter of the block, by actuating the wing nut 38.

N the device may be adaptedto capsjofdifferen't sizes, or strain applied to hold the cap in position;

, By this mean'sthe cap is firmly held while being operated on,'a's' will be obvious.

Another standard 43 islikewise provided and having a transverse head 44 provided with apertures in the ends to receive portions of machines to be operated on, for'insta'nce a valve stem 46 as shown in F ig. 6, each end being provided with a set screw'47to enable {the article being operated on to "firmly held.

.-In Fig. 8 another form of-holding edg i shown comprising astandard 7O to engage in the aperture 34 and having a transverse Thead 71 from which'spaced clamp bolts 72 rise and operatethrough a clampingmenr 7 her 73, springs 7 4 being disposed around the ternally of the members 37. By this, simple bolts between the members 7lfand 73 and clamp nuts 75 engaging the bolts '72 exmeans standard, 70 may be supported by the set screw 42 in the member 30 and an'object to be worked on supported between the mem- 1bers71and73. f

i Attached at one end at 48 to the member. 30 isa flexible member, for instanceachain 49 having a loop. nut 50'at the outer end.

A rod '51 threaded atone end to-engage the nut 50, extends through'themember 30'a'nd is formed with a turn handle at the other end and with an intermediate stop 53 to bear againstthe lower face of the member 30.

After the work, for instance the axle eas ing 33, is disposed within the recesses 32 of the ;standards;3l the chain 49 is passed around the casing and the bolt 51 passed up through the member 30 and engaged with the nut 50, and strain applied by rotating the rod byits handle 52, the stop 53 holding the rodfrom longitudinal movement, as will be obvious.

One of the standards 35 will preferably be inserted in the socket 34 in the member 30 and adjusted with its block 36 beneath the casing 33,- and coaoting with the standard 31 to support the casing.

By this means the work will be firmly held in position to enable it to be assembled or disassembled, or otherwise treated.

In Fig. 3 at the right, a simply constructed vise device is shown adapted to support the piston 54 and connecting rod 55 of an internal combustion motor, consisting of a stock 56 to engage in the socket 34, and provided with a transverse head 57 having upstanding standards 58. Y'

The standards 58 are provided with transverse threaded apertures to receive clamp screws 59 to bear within the pin openings of the piston, and thus hold the latter in position between the standards.

Set screws, one of which is shown at 60, are tapped through the head 57, to bear beneath the piston 54 and prevent the latter from tilting on the holding screws 59.

Attached to the transverse lower members of the leg portions 11 is a tubular guide and support 61, and telescopically engaging in the guide is a stay member 62 preferably tubular, and rising from the stay member at its free end is a'tubular standard 63, and slidably engaging in the standard IS an extension member 64 adjustably supported in position relative to the member 63, by a set screw 65. i

At the juncture of the members 62 and 63the lateral extensions 66 are connected as shown in Fig. 3 to form supporting feet, and at its upper end the extension member 64 is formed with a lateral head 67 to provide a support for the work: held on the standards 31-32, for instance the casing 68 for-the main drive shaft and the braces 69 of a motor driven vehicle, while theaxle casing 33 is being held in position as above lUU whereby the difierent parts of a machine can be effectually held in position while being operated on and in convenient relative position so that it is not necessary to move from one part of the shop to the other, or carry the articles to be treated from one place to another.

For instance Fig. 1 illustrates the manner of holding an engine casing in position while the crank bearings are being burned in, or otherwise treated. Fig. 2 illustrates the manner of holding the rear axle casing and its associated parts in position. Fig. 3 likewise illustrates the manner of holding the piston head and the connecting rod in position while being acted upon.

The improved device is simple in construction, can be inexpensively manufactured of any suitable material and of any suitable size, and operates effectually for the purposes described.

The preferred embodiment of the invention is disclosed in the drawings and set forth in the specification, but it will be understood that modifications within the scope of the claims may be made in the construction Without departing from the principle of the invention or sacrificing any of its advantages.
